Just tried to rebuild the containers with this applied and they're failing to build for an unrelated reason --

build/ansible/roles/docker/templates/ubuntu1804_sharedlibs.Dockerfile.j2

Line 90 in c9210ef

curl -sL https://zlib.net/zlib-1.2.11.tar.gz | tar zxv --strip=1 && \

is failing because https://zlib.net/zlib-1.2.11.tar.gz no longer exists. I'm guessing it was removed after the recent zlib CVE. I'll add a commit here to bump to zlib 1.2.12 and try again.

Now deployed.

The Jenkins job had the expected zlib version hardcoded:
https://ci.nodejs.org/job/node-test-commit-linux-containered/31647/nodes=ubuntu1804_sharedlibs_zlib_x64/console

18:29:22 ++ out/Release/node -pe process.versions
18:29:22 ++ grep zlib
18:29:22 + ZLIB_VERSION='  zlib: '\''1.2.12'\'','
18:29:22 + echo 'zlib Version:   zlib: '\''1.2.12'\'','
18:29:22 zlib Version:   zlib: '1.2.12',
18:29:22 ++ echo zlib: ''\''1.2.12'\'','
18:29:22 ++ grep 1.2.11
18:29:22 + '[' X = X ']'
18:29:22 + FAIL_MSG='Not built with zlib 1.2.11, exiting'
18:29:22 + echo Not built with zlib 1.2.11, exiting
18:29:22 Not built with zlib 1.2.11, exiting
18:29:22 + echo 1..1
18:29:22 + echo 'not ok 1 Not built with zlib 1.2.11, exiting'
18:29:22 + exit -1

I've updated the job to expect 1.2.12.

New test build: https://ci.nodejs.org/job/node-test-commit-linux-containered/31648/

New build is green.
